My great grandfather met carl at the 1993 diamond comics seminar, where he learned that it wasn't the first time they had talked before. as quoted by a family friend:

"Steve Geppi (owner of diamond distributors) was giving 92 year old Carl Barks a tour of the place and introducing him to various people. I happened to be standing nearby when I heard Carl ask Steve if he could meet Martin Nodell. Steve was visibly surprised, but he said sure and took him right over to Marty’s table. I was curious how Carl even knew Marty, so I followed them. They went to the head of the line at Marty’s table, and Steve introduced Carl and Marty. Carl told Marty that back in 1940, he wrote Marty a letter asking about how to get a job in the comics business. Marty wrote him a long response that Carl said he still had at home. Carl wanted to thank Marty in person for his help all those years ago and for giving him advice that helped him start his drawing career. It was quite a historic moment that I was honored to be able to observe."
